A new paradigm of easy-to-access multiple resonance (MR) emitter is constructed by simplifying multiborylation through amine-directed formation of B−N bonds, while introducing an additional para-positioned N atom to trigger the MR effect. The proof-of-concept molecules, m[B-N]N1 and m[B-N]N2, exhibit impressive maximum EQE values of 36.0 % and 33.4 %, with narrowband emissions at 480 and 486 nm, and FWHMs of only 26 and 32 nm, respectively.

具有窄带发射的 BN 稠合多环芳族多重共振发射器的胺定向形成 BN 键

通过胺定向形成BN键来简化多硼化，同时引入额外的对位N原子来触发MR效应，从而构建了一种易于访问的多共振（MR）发射器的新范例。概念验证分子m[BN]N1和m[BN]N2表现出令人印象深刻的 36.0 % 和 33.4 % 的最大 EQE 值，在 480 和 486 nm 处具有窄带发射，而 FWHM 仅为 26 和 32 nm，分别。
